well i have been doing what i always do with my vehicles. yes tinkering. well over the past few weeks i have been experimenting with different gaps on the plugs and so far .035 seems to work best, but that is not my concern. I am concerned that my soul has only 8k on it and the plugs are already rounding off, and yes they are copper and they are champion. i lost the number, but they are a weird almost 2 inch reach plug. I want to find a fine wire platinum or iridium to replace them. also before anyone suggests any other 1.6 plug they are way different. searched and searched i cant find anything. If it wasn't for these plugs this would be an ultra low maintenance engine.
